Abstract (en)
[origin: EP0397273A2] A process for oligomerizing light olefins in order to produce C5+ hydrocarbons is disclosed, which essentially comprises the following steps: (a) a reaction feed stream containing light olefins is pre-heated up to a temperature of at least 230 DEG C; (b) the pre-heated feed stream is oligomerized by means of a conversion catalyst in two or more reactors in cascade, with the reaction product being cooled at the outlet from each one of said reactors; (c) from the reaction product from the last reactors, C4-hydrocarbons are removed in a distillation tower, with the desired C5+ hydrocarbons being obtained at tower bottom, and an at least partially liquid stream containing (C3-C4)-alkanes being obtained overhead, characterized in that at least one portion of said liquid stream containing (C3-C4)-alkanes is recycled to one or more side point(s) of each individual reactor used; inside each one of said reactors the catalyst layer is subdivided into two or more beds, with said recycle stream being injected between said beds, in order that the desired temperature profile is maintained along the concerned reactors.
